lie ,it known vthat I, Aman-iu B. BREEZE, Va citizoi'i of tlievUnitedStatenj and residing at "incinnati, in the county oi" l-lan'iilton andStat-- of Ohio. have invented al'u'ew and useful Improvement in l)'r.rg{-Linl l De ices, of which the follmx'ilrjg Specilieation is` aA fulldisclosure.

A invention.relates to an impro-vcd drag link device and morepa'rtiiznlarly, to the means .f'(- i".-;um orting the socket, hearingYpiete for a knuckle joint in the (nd of a steel tube. -lerctofore itlhas: heen customary toprovide ancnlarged tube 01nd for this purpose, asa ineans of providing a :shoulder or scat for the. Ainner socket piece.This le quired splicing a larger tui e end on a Smaller tube, or:rs-waging process, or olertric .vclcling7 or boring 'operations7 makingthe job undulyA :expensive and weakeningA the lnrged to form theShoulder abut-nient.

'.lho ohject of lnyninvntion is to enable the use of -a singlel piece..tube, preforaliily of uniform. diameter, the seat for the inuor hearing'piece boing formed .integral 'with the tobtl upon a uniform(ilianietersection of the l'.n l e,:.|.nd to forni Seats of this fzllzuzuztoi" by a. convcniontandV inexpensive im-;tliml. producing aStronger and better apparu-'ng doi/ice as nell.' f

I' have shown three of such tongues..the counter- 'Sunk front ends of which constitute the siats or shoulders'6, within the tube, and two or more of such seats may be .formed as-dcAsired. i C* lVllile my invention' is not"limitedto this manner of,-forniing Seats b vvto'olfas itiiuayA oliviouslvv lio a hand inc thod,there are ail- Vinit-ages in this die"v andfpunoh operation readily api:u'erit7 to-\ vitz,"th'e tm'fgjl'ie are all pushed inward tothe-Samb 'i'rfreeo that the sont.`A are uniform". the tube is iiot''lifto'rted.'ferred= to punch" in' "thev front-'ends .of' the The innerbi'uf-ingpieco cin'pi e# the loir:- aiuniforential boss 8having"adlanmter {ittingr a oirrle vtangentiall-ly'de rolatisely to the'inner odge-S'J of the". indica ed in dotted linesl 9,-Fig. l. and asshowrjif'n Fig. l, so that. this boss Supl portizdhy thv inner 'sontSli'rfaoe inf :L position r-.mmcntrio to tho tube, The Socket hearingprdper, 1l), integral with boda 8, is rircular, and of a. dianietrto litthe normal diameter of the tube, itamarginal periphorji' 1i, dfined lythe sinalhr diazs'ietr-.r boss S, boing; hold fndwise against the seats,where.- liy tho boga is sup1iorteil.conientricall y on seats axialand'radial to the tube.

site ends passing through orifices in the outer end of the tube.

The tube is formed with the opening 19 for the steering gear rod 20 onthe inner end of which is the. ball or knuckle :21, having bearings onthe right and left hand socket pieces.

It will be seen that this makes a very strong and simple device forSecurely and concentrically supporting the socket pieces and that it isproduced by a very cheap and efficient method.

Any strain in an axial direction on the inner socket piece will beresisted in the same direction by the seats, the tongues forming theseats being,r prevented from moving inwardly because the inner edges ofthe tongues vrest upon the periphery of the boss H, as shown in Fig. 1.

Ordinary steel tubes can be employed and they can be fitted up veryrapidly at a minimum` cost.

Having described my invention, I claim:

1. A drag link device comprising a tube 8. A drag link device comprisinga tube of uniform diameter formed with socket piece seats struckinwardly from and integral with the tube, and a socket piece heldagainst said seats. f

i. A drag link device comprising a tube of uniform diameter havingintegral members struck inwardly from the tube, a socket hearing piecehaving a circumferential boss fitting between the inner edges of Saidmembers, and a larger diameter socket portion hearing endwse against theends of said men'ibers.

5. A drag link device comprising a tube having inwardly struck tonguesforming axial seats and diametrvical seats within the tube, and a socketpiece, one portion of which is held against the diametrical seats, andanother portion is Aheld between the axial seats formed by said tongues.

A drag link device comprising a tube indentured near one end toconstitute a seat for a. member to be inserted into the tube end, thetube portions upon opposite sides of said indenture being of the samediameter. and a socket piece concentrically held within saidl tube endand against said indenture.

In witness whereof, I hereunto subscribe my name, as attested by the twosubscribing witnesses.
